Looking for help from Network Guru

[George M]

I found a need for a second linux computer. I have a couple of Lenovo ThinkCenter mini computers and an old pc that hasnt been used for a few years. I started with one of the mini's and installed the latest Ubuntu. It connects to the Lan just fine but will not connect to the internet - either wired or WIFI. So I tried it with the other mini --- same thing. I thought that has to be weird but I then tried it on the old PC.
Same thing. Any new Linux (Ubuntu) install connects fine to Lan but will not connect to the internet. I have an Asus router if that matters.
Could really use some good ideas on how to track down the problem here.

Here primarily use Ubuntu Linux mostly and mini Lenovo Tiny computers. M93A's and M9000's. Today these are running Ubuntu 24.04.

When you installed Linux did you configure the updating via the Internet when installing Linux?

It is plug n play.

Try a ping to google in a terminal window and post it here.

Here is a ping from my Linux laptop.

Hi Pete, good to talk to you again.
When I installed i could not update via internet because I never could get a connection.
Ping doesn't work because, again, it doesn't go anywhere. What is strange is that if I ping www.google.com I get this:
PING www.google.com (192.0.0.88) 56(84) bytes of data ---- and it sits there until I cntr/c
If I ping the address for google I get the same thing.
I' beginning to think it is something in my router that is blocking any Linux install from connecting to the internet.

 

[George M]

I think I found out what is going on. I have my router set up to use NordVPN. When I turned off the VPN i was able to connect to the internet. That is a work around, but how do I get the linux machine to work through the VPN?

 

[pete_c]

My Linux computers have PIA (Private Internet Access) installed and I use it occasionally. Some sites block the IP's utilized by VPN.

Try installing the NordVPN client on the computers.

Here the router runs OpenVPN server (for access from the internet to home), Maxmind (PFBlocker) GeoIP blocking, Snort, Squid, Squidguard,

It was all my router and the VPN. With other computers they are added to the default VPN site automatically. But with the Linux ones, for some reason. I have to go in and manually add them to the VPN site. Once I do that then all is well.
